I saw no difference in green response in any of my test areas; zip, zero, nada. I made 2 purchases based upon the dozens and dozens of posts from "the owner or friend of the owner-Lawn132012" (my opinion). So based upon my use and experience, it was a complete and total waste of valuable time and money.
Does it have an affect on the root depth and thickness, worm and "bug" population, help lawns during the summer stresses; I don't know. I made my purchases based upon the "WOW" green up response. There was none, so I feel I bought snake oil.
Obama is so bad, Kenyans are accusing him of being born in the USA.
